Effective January 1, 2023, Miami-Dade County implemented stricter standards through Ordinance 22-83, prohibiting conventional (Type 1) systems for new installations. All new systems must meet Type 2 (secondary treatment), Type 3 (advanced secondary treatment), or Type 4 (Florida Keys Nutrient Reduction) standards depending on your property type, wastewater volume, and proximity to surface water bodies.
What is different about installation in Miami
New septic installations in the City of Miami are uncommon because most of the city is on public sewer, and Ordinance 22-83 bans a new septic system wherever a gravity sewer or force main abuts the lot. The 2,772 septic parcels the County counted in 2020 are mostly older homes; new systems are usually replacements on streets without sewer.
Where septic is allowed, today's standard applies: an engineered design approved by DERM, a treatment unit meeting NSF/ANSI 40, 245 or 350, a drain field at least 36 inches above the wet-season water table, and 100 feet from any surface water.
What the numbers say about Miami
- The County's 2020 billing data counted 2,772 parcels with septic systems in Miami, about 2% of the county total, against about 223,826 homes. (Miami-Dade WASD, 2020 data) (U.S. Census ACS 2020-2024)
- In the County's 2018 groundwater study, 156 of Miami's 1,603 modelled residential septic parcels (10%) already reached peak groundwater within 42 inches of the surface; the projection for 2030 was 177. (Miami-Dade, 2018)
- The County asks residents of municipalities such as Miami to check sewer status with their local water and sewer department. (Miami-Dade WASD)

System Types and Design Requirements
Miami-Dade County requires advanced treatment systems for all new installations. The system type required depends on several factors:
Type 2 Systems:
- Designed for secondary treatment
- Serve single-family homes or duplexes generating less than 500 gallons per day
- Must be located at least 1,000 feet from surface water bodies
- Most common for standard residential installations
Type 3 Systems:
- Meet advanced secondary treatment standards
- Apply to multifamily properties and other uses not exceeding 1,000 gallons per day
- Also require a minimum 1,000-foot distance from surface water bodies
- Required for larger residential or small commercial installations
Type 4 Systems:
- Adhere to Florida Keys Nutrient Reduction Treatment Standards
- Required for uses that do not qualify for Type 2 or Type 3 classifications
- Most stringent treatment requirements
- Required for properties near sensitive water bodies or high-density developments
Critical Design Requirements:
- Setback distances: Minimum 100 feet from any surface water body and 50 feet from all property lines where public water is unavailable
- Drainfield elevation: The bottom of the drainfield must be at least 36 inches above the wet season high water table
- Reserve drainfield area: A 50% reserve area (equal to half the size of the initial drainfield) is required for future system expansion or replacement
- Soil conditions must support safe effluent absorption based on percolation rates and soil texture

What is the 50% reserve drainfield area requirement?
Miami-Dade County requires a reserve drainfield area equal to half the size of the initial drainfield. This reserve area is set aside for future system expansion or replacement, ensuring adequate space for system maintenance and upgrades.

What happens after installation is complete?
After installation, the county health department performs a post-installation inspection. Once approved, the system must be registered with Miami-Dade County (required as of January 1, 2024). We coordinate all inspections and registration to ensure your system is properly activated and compliant.
Miami questions
Can I put a new septic system on a City of Miami lot?
Only where no public sewer is available at the property. Ask the utility for a sewer availability answer first; if a line abuts the lot, you must connect.
